Palo Alto Networks App for Splunk 5.3.1: "pancontentpack threats" command returned error "External search command 'pancontentpack' returned error code 1."?

After we upgraded Panorama from 7.1.x to 8.0.5, the "pancontentpack threats" command from Splunk is no longer work. However, "pancontentpack apps" still work and returns result.

Our environment
Splunk Enterprise 6.5.3
SplunkforPaloAltoNetworks 5.3.1
Splunk_TA_paloalto 3.7.1

I also upgraded the PaloAlto App and TA to the latest version, but it still failed for pulling threats content.

This issue has been resolved in verion 6.0.0 of our app. Please upgrade and let us know if you still receive an error.

Hi Brian, any fix or workaround for this issue without upgrading the TA to 6.0.x?
